Chemical Structure

2-Octadecyl-1-docosanol CAS 182176-42-7 chemical structure

Description

2-Octadecyl-1-docosanol (C40H82O) contains a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

2-Octadecyl-1-docosanol (CAS 182176-42-7) is a high-purity analytical reference standard with the molecular formula C40H82O and a molecular weight of 579.08 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
